Is there a way to test the fuel injectors on a 2.8 ?As you may or may not know you need to remove the Intake Plenum to get to 4 of the 6 injectors. So its not like I can run the car and remove an injector wire to see if there is a change in RPM's.Any help please.

After searching the web I found something by Roy, BAT Auto Technical.Any who I checked at the injector 4 plug connector for resistance. The A & B terminal showed nothing and the B & C terminal showed 4.3 ohms.So I started my car til the fan kicked on.I then turned the car off, and removed the Intake Plenum to check each fuel injector. Here are the results:

just called Auto Zone ÃƒÆ’Ã†â€™Ãƒâ€ Ã¢â‚¬â„¢ÃƒÆ’Ã¢â‚¬Â ÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢ÃƒÆ’Ã†â€™Ãƒâ€šÃ‚Â¢ÃƒÆ’Ã‚Â¢ÃƒÂ¢Ã¢â€šÂ¬Ã…Â¡Ãƒâ€šÃ‚Â¬ÃƒÆ’Ã¢â‚¬Â¦Ãƒâ€šÃ‚Â¡ÃƒÆ’Ã†â€™Ãƒâ€ Ã¢â‚¬â„¢ÃƒÆ’Ã‚Â¢ÃƒÂ¢Ã¢â‚¬Å¡Ã‚Â¬Ãƒâ€¦Ã‚Â¡ÃƒÆ’Ã†â€™ÃƒÂ¢Ã¢â€šÂ¬Ã…Â¡ $50 dollars each for injectors

An EGR is either $31. or $119 ÃƒÆ’Ã†â€™Ãƒâ€ Ã¢â‚¬â„¢ÃƒÆ’Ã¢â‚¬Â ÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢ÃƒÆ’Ã†â€™Ãƒâ€šÃ‚Â¢ÃƒÆ’Ã‚Â¢ÃƒÂ¢Ã¢â€šÂ¬Ã…Â¡Ãƒâ€šÃ‚Â¬ÃƒÆ’Ã¢â‚¬Â¦Ãƒâ€šÃ‚Â¡ÃƒÆ’Ã†â€™Ãƒâ€ Ã¢â‚¬â„¢ÃƒÆ’Ã‚Â¢ÃƒÂ¢Ã¢â‚¬Å¡Ã‚Â¬Ãƒâ€¦Ã‚Â¡ÃƒÆ’Ã†â€™ÃƒÂ¢Ã¢â€šÂ¬Ã…Â¡ they need the O.E. #'s (while running the car earlier I removed the air line going to the EGR and I had very smooth acceleration plus I wanted to check the vaccum there. And I checked how much vaccum operates the EGR. and it was not in check with the service manual, Maybe there is a pin hole or something. There is 200,000+ miles on it, so I figured why not replace it)

injector 5 is bad, its at the least weak requiring too much juice to operate which takes away from its mated injector. The only solution is to replace it, clean all the electrical connectors, the injectors should recieve new o rings for the manifold and be cleaned (carb dip for the bottom (pintle area) of the injector.
